>> i'm piers morgan and this is cnn. >> this is cnn breaking news. a final gun battle. suspected marathon boston bomber, surrounded by authorities in a boston neighborhood and he eventually gives himself up. so the week began with a deadly terror attack at the boston marathon concludes with cheers for local, state and federal authorities. >> hello, everybody. i am at the cnn center in atlanta. >> and welcome to cnn's continuing coverage of the capture of the final suspect in the boston marathon bombing. >> friday night's dramatic event followed a massive manhunt in

the boston area. after thursday night's gun authorities that resulted in the death of his older brother, dzhokhar tsarnaev, he eventually gave himself up. and anderson cooper got all the details from boston's police commissioner, edward davis. >> he was severely injured, and most likely the shoot-out that occurred last night, there was an exchange of gunfire with police this afternoon. >> so there was an exchange of back and forth of gunfire this afternoon in the boat location, is that correct? >> that's correct. that's what i have been told. the boston police officers and the massachusetts state police

and federal agents surrounded the boat, and there was an exchange of gunfire, and they were able to remove the suspect from the boat. >> president obama spoke to reporters shortly after dzhokhar tsarnaev was captured. he wanted to find out why the brothers carried out the bombing plot and whether anybody else may have been involved. >> one thing we do know is that whatever hateful agenda drove these men to such heinous acts will not and cannot prevail, whatever they thought they could achieve they failed, and they failed because the people of boston refused to be intimidated, and because americans we refused to be terrorized and they failed because we will not waiver from the character and the compassion

and the values that define us as a country, nor will we break the bonds that hold us together as americans. that american spirit includes staying true to the unity and diversity that makes us strong, like no other nation in the world. >> the governor of massachusetts added his thanks, but as the celebration expanded one authority said, if you want to thank us, just go home. >> and they announced they had their man and it had been a terrifying week, but that fear is now gone. >> reporter: it was really just

moments after the news came that police had captured the second suspect in the boston marathon bombing. the streets in boston here erupted in jubilation and cheers, and we ran into a group of 400 college students from the university that filled the tkoerpl dorms, and they were waving flags and chanting, "usa, usa." some spoke about how scared they were, and they said now they can go back to class and they can rest again. it's around the world. we heard a story of a flight that was on going while the news broke, and the pilots announced

suspect number two and the entire plane erupted in applause. but it's being felt everywhere. but we have to remember this is a city still reeling from such a tragedy. at this hour you have 58 people still recovering from the injuries in the attack in boston area hospitals, and three in critical condition and two are children and you still have the four beautiful lives lost. the officer murdered last night, and the 8-year-old beautiful boy, martin richard who died from the attack, and the girl, krystle campbell, and the chinese student studying here, those four people lost. the city is still suffering such a tragedy and as such a long way to go. the successful manhunt ended

in a backyard in watertown. and in the end the man that caused people in the boston area to hide in their homes, he himself was hiding in a small boat. we have exskhraoclusive details. what will happen when the sun comes up in a couple hours, where does the investigation go where you are? >> reporter: john, we can tell you the parameter has been tightening here. they really released a lot of the streets and opened up the streets and the parameter here brings us to right behind me. we can't go beyond this. they are going to go through the area and process evidence and going through the boat, of course, combing through that for evidence, and dusting it and doing all sorts of the things where he was holed up for several hours, and that's going to be a key piece of the investigation. and they are going to be

question tsarnaev, and asking what led to the standoff and all of that and that's the beginning of the investigation as far as the questioning of him, and he will probably be hiring an attorney in the next couple days, too. that will play out legally as they comb through the evidence for evidence, and they can be looking for additional weapons in the neighborhood. while he was on the loose, they were very concerned. authorities were very concerned he might have explosives on his body. could their be explosives left somewhere in the neighborhood that were undetonated. >> there's a lot to do yet and many days and weeks to go. what was amazing when i was watching our coverage you got so close to the shoot-out and you could see it and you heard the

negotiators speaking with tsarnaev. tell us some of the things you got to see. >> it was pretty incredible. we were trying to get close to the scene. it was tough to do it even on foot. we had to walk more than a mile after our vehicle was stopped and we snaked through allies and back lots. our producer had a map, a navigation in his smart phone and was pointing us where we could go to get closer. that's how we navigated, we got there and went through allies and back lots away from where some of the authorities had blocked streets and we got to a back alley and we came around the corner and we could see the boat right there, and it was illuminated by the light police put on the boat, and we got closer and started filming, of course, and we could hear them

talking on the loud speaker saying come out with your hands up, we know you are in there. and they were negotiating this. and this was after the gunfire. this is after the flash bangs they sent in there to try and disorient him. he was wounded possibly from this exchange or from 24 hours earlier when he and his brother were in that exchange. we don't know. it was a violent situation. after that, john, they were trying to negotiate, and of course that did end up being successful and they ended up capturing him alive. >> just walk us back to the news conference which was held by the authorities there by the governor, and by the police commissioner when they basically lifted the stay indoors order, and they said, listen, you know, it looked as if they were saying he got away, and then suddenly, almost the moment they stopped speaking, gunfire erupted and

this took a turn which was dramatically different to what everybody had expected. >> reporter: dramatically is certainly the right word, john. we were thinking the same thing. this news conference, they appeared almost despondent, like, gosh, we thought we had him, and we thought we would get him and it sounded like he got away. we left there thinking this is not going anywhere for the moment, and literally minutes later, as if it was timed to go with the end of the conference, about a mile away from here, we hear the gunshots and we see police vehicles whipping around and doing frantic u-turns and speeding back into the neighborhood and you have the standoff and dramatic ending. you would think they staged the news conference to throw us off

the track, and they were not, but it was surreal. >> that's how it seemed at the time. brian, you have done great reporting and had a really long day, and we appreciate you staying with us. it's ten past 5:00 in the morning there, and thank you for the live report and all the reporting. >> many thanks, john. thank you. and as the word of tsarnaev capture spread, and that's where the finish line of the boston marathon was and where the bombs went off that killed three people. and as we continue to see the pictures of the release and the memorial there, and that's a reminder of the victims, and those still on the road to recovery from the bombings. >> more than 50 people remaining

in area hospitals, and some had injuries to their lower extremities, and the bombs targeted the spectators for the most amount of harm and bloodshed by the way they were placed, and we want to find out what the family and friends of the two alleged bombers think of these two young men, and we will have more on that when we come back in just a moment. >> stay with us. angie's list is essential. i automatically go there. at angie's list, you'll find reviews on everything from home repair to healthcare

written by people just like you. if you want to save yourself time and avoid a hassle, go to angie's list. at angie's list, you'll find the right person to do the job you need. and you'll find the right person quickly and easily. i'm busy, busy, busy, busy. thank goodness for angie's list. from roofers to plumbers to dentists and more, angie's list -- reviews you can trust. oh, angie? i have her on speed dial.

welcome back, everybody. you are watching cnn's continuing coverage of the capture of the second suspect in the boston marathon bombings. >> the second suspect in boston's marathon attack is in custody after gunfire erupted friday evening in the boston suburb of watertown where he had

been on the run. he had put up a fight after finding himself surrounded by police. he had been hiding in the boat in the backyard of a home. this is a picture of him in an ambulance as he was taken away. he is now considered to be in a serious condition in a boston hospital. the picture that is emerging of the brothers, it's in sharp contrast to what they allege to have done. two family members have said that their friend just didn't seem like a killer. >> when you spoke to him in january, no indication at all -- >> no indication at all. none. none. quite the opposite. like i said, he was a very genuine person. he was n't a genuine person. >> now, yes, he's a bad guy. who knows his reasoning, and he

is a really bad guy, but the way i was trying to portray his image was of a good person and something nobody would suspect him of, and -- >> so what you are saying is what he is being accused of is not the person that you knew? >> yeah, basically. pretty much. >> the parents of the suspect said neither of their sons talked about or showed any inclination towards terrorism. >> my youngest won, he was raised in america, and my oldest son, he is, like, really -- never in our house, nobody ever talked about terrorism. my son, he got involved in the religion, you know, like -- religious politics five years ago, so he started following his

own religious acts, and he never told me that he would be like on the side of jihad. they knew what my son was doing, and they knew what actions and what sites on the internet he was going. how could this happen? they were looking at every step of him, and they are telling us today that this is a terrorists act! >> translator: somebody framed them. i don't know who exactly did it, but somebody did. and being cowards, they shot the boy dead. there are cops like this. when you try calling the younger one, the phones are off? all phones are switched off. i can't get to my brothers. one is a gate lawyer and i can't get through to him. i want to get more information. those are my kids, you understand? i am afraid for my other boy. maybe he will be shot dead, too,

and they will say he had weapons. you don't find weapons in a garbage dump. i have nothing more to say. it's all because i am afraid for my son and his life, and they should arrest him, maybe, and bring him alive, alive, and justice should decide who is right and who is guilty. >> reporter: you have been living there for a long time and you have had any complaints about the justice there? >> translator: no, never. i never faced it. how can i see the justice there, i never had any problems. >> reporter: what did your son tell you? >> he said everything is okay. i asked him how is dzhokhar, and i asked if helped him? this in life, a person that doesn't learn is working, working hard. that's why i am always telling

them, study, study, study. >> reporter: did you talk about the explosion and what happened there? >> translator: no. not at all. thank allah that they were not there. what explosion? i can't imagine who would do this. whoever did this is a bastard. i have nothing else to say. >> one of the uncles went on live tv friday, upset, and pleading for tsarnaev to give himself up. he said the men have brought shame to their family and the entire chechen ethnicity.

>> i want to start, and i will finish with, first, the only purpose here, our condolences, and those that were murdered and those that were injured this boy, this chinese girl, this young 29 years old girl, i have just been following this, i have been following it from day one, which never ever would imagine that somehow the children of my brother would be associated with that. so it is a tragedy. again, i don't know. this family does not know how to

share their grief. >> as we have been telling you the bombing suspect families' routes go back to the suspect of dagestan. and they have been searching for clues to a possible motive. and nick, explain to our viewers exactly where you are right now and what you have been finding out about the suspects and the time there in dagestan. >> reporter: i am standing out school number one here in the capital of the russian republic, dagestan. we saw a register that made it quite clear that in september of 2001, the siblings came here, two brothers and two sisters, studied until march 2002, when it says they all left for america. and it leaves a gap in the

timeline. and now the deceased bomber says, he didn't know up in the united states until sometime in 2006. now, he could have perhaps have gone on a short term visa, but there is a hole there which i am sure officials here and in the u.s.s will be looking into to see if that period of time may have caused some kind of change, or if he was in russia where extremism is common. in 2001 to 2006, we're talking about if he was in dagestan, he would have been surrounded by violence which began to spill over from the second war, and taking roots in this impoverished part of the world, attacks on policemen, and militants were fighting, and

increasingly infiltrated by the extremist radicals. something russian security said is long talked about here, and it has been dismissed by some, and perhaps they would not have to enter into negotiations with them. a complex situation here. and if he remained here, he could have been influenced by that. >> as you talk about the swirling violence and extremism, and as you talk to people there in the capital, you have detected or are you aware of a kind of anti-american strain there in dagestan? >> reporter: well, there are three elements to this. disbelief certainly that the brothers were involved in the events in boston, and a strong russian nationalism, and you see many russians here, and the

third element of course is how violence is continuing here. we have seen the radicals, and still outbursts here, and what used to be a problem for chechnya has been a problem for others. and there's an expressed belief that somehow the brothers were involved, and maybe there was a link and how damaging that could be for a region really struggling to get back on its feet and into a peaceful time. >> so many questions for the authorities, but among them, what exactly did tsarnaev do last year, and what do we know if anything about his movements, where he went and who he met with?

>> reporter: certainly i think the most interesting thing about his personal timeline with the gaps in it. we do know he saw a shop keeper, but in january of last year where he was said to be in russia, the shop keeper said he was there helping his father out in the refurbishing of the apartments to make money. aside of him being there for a harmless reason, there were some months where people will ask where was he, and this came after an interview by the fbi after a request from a foreign government. everybody says he was a golden student. >> always appreciated. great reporting. thank you.

did they act alone? that's the question so many people are asking at this hour. our security analysts told anderson cooper it's very likely the brothers had help carrying out their plan. >> i think it's very interesting that they were able to detonate two bombs almost simultaneously. i think that's pretty hard. it suggests either practice in the united states or training elsewhere or perhaps both. we have had terrorists who have gone overseas and tried to detonate bombs in the united states, for example, the times square bomber, he was trained and he drove his suv into times square and detonated the bomb and it didn't work. even with training people don't sometimes get it right. the idea that these two read a recipe on the internet and built two successful bombs, that's very unlikely. that's the first question. and then the other question

president obama raised in the briefing, how do they become radicalized. and we look at ft. hood, and what these guys were doing on the internet and who they e-mailed and what they were reading and what kinds of things they were downloading will be key to the question of motivation. and finally, anderson, what was the older brother doing in russia for six months. we have seen in the past, an american citizen, a naturalized came to the country, and he became trained on how to use bombs. >> this has been a developing story in boston, but now there is breaking news. officials in china say the death toll from saturday's earthquake has topped 100. more than 3,000 people injured

when the 6.6 magnitude quake struck. we will continue to follow this story. we will bring you all the latest as we know more. it's approaching 5:30 in the morning here on the east coast. you are watching cnn's continuing live coverage of the capture of the last suspect in the boston bombing, the boston marathon bombings, i should say. it has been a very intense past 24 hours in the boston area. we will take a very quick break, and when we come back, we will run through how the dramatic events of the day unfolded. let's get a recap, merv. [ merv ] thanks, other merv. mr. clean magic eraser extra power was three times faster on permanent marker. elsewhere against dirt, it was a sweep, with scuffed sports equipment... had it coming. grungy phones... oh! super dirty! and grimy car rims... wow! that really works! ...all taking losses. it looks like mr. clean has won everything.

welcome back. you are watching cnn's continuing coverage of the capture of the second suspect in the boston marathon bombings. >> it's been quite a tragic and very tense week in the boston area, and especially so during the past 24 hours. >> erin burnett has a look at how the dramatic events unfolded over the past day. >> today we are enlisting the public's help to identify the two suspects. >> reporter: shortly after 5:00 p.m. yesterday, fbi special agent in charge releases these images of the two men in the boston marathon bombings. hours later a. second photo circulated online of suspect number two walking away from the bombing.

a little after 10:00 p.m., two men are spotted at a convenience store in cambridge near the massachusetts institute of technology. >> we had to hear 100 gunshots. >> reporter: we learn a 26-year-old police officer from mit has been shot and killed. moments later boston police begin a high speed chase, and then a carjacking, and the suspects throw explosives from the car. >> we could hear them yelling. >> reporter: at approximately 1:23 a.m., residents in watertown are jolted awake as dozens of police exchange gunfire with the two suspects. >> it was like, boom, boom, boom, three big bangs. >> reporter: a fierce fire fight with explosions follows, and

leading to the death of suspect number one, and suspect number two escapes on foot. by 3:45 in the morning, massachusetts state police warned watertown residents to stay in their homes, lock their doors as police begin searching door to door. a little after 5:00 a.m., as day breaks, the city of boston begins to move into a lockdown, suspending mass transit and asking businesses to remain closed. >> it's important for people to remain indoors and keep the doors locked. >> reporter: authorities identify the suspects as brothers, and at 11:55 a.m. the city of boston is at a standstill, and the relatives of the two suspected bombers speak out. >> turn yourself in and ask for forgiveness. >> reporter: 3:42, investigators find significant amounts of

homemade explosives in watertown. >> we are asking the public to remain vigilant. >> reporter: 6:00 p.m., the lockdown is lifted. people can leave their homes. and less than an hour after the lockdown is lifted, shots are fired and police go to the scene. >> reporter: i just heard what sounded like multiple assault rifle shots. >> reporter: and then cornered on a boat in watertown. hundreds of agents surround the suspected bomber, and many around boston break out in tears, followed by the crowd coming to the streets to celebrate. >> now is one of the brief glimpses we got on friday night of the suspected bomber. and this was tweeted by one

affiliate. and it shows dzhokhar tsarnaev's face after the shoot-out in water town. and then pamela is where the bomber has been taken. when can we expect an update about his condition? >> reporter: we are hoping for an update soon. authorities have not released any information about that. right now the hospital is declining interview requests, and referring everybody to the fbi, and the fbi is taking all the questions. we hope to learn more. as of now we do know that the suspect is in serious condition, and he experienced a substantial amount of blood loss, we are told, but we don't know the nature of his injuries. >> what are the security situations there?

we saw an ambulance arrive, and it was escorted by ten police officers and other law enforcement seen there as well, and what is the situation right now? >> reporter: there is a large security presence, not only at this hospital but at hospitals around the area there was security. we were at mass general hospital, and there was lots of security around. there are five security officers outside the hospital here, and there are two inside the hospital, and there may be more, we just don't know. these officers have been here throughout the night. they will likely continue to be here as long as the suspect is here being treated. >> to that, this guy would have to be the most wanted man in america right now. how will the hospital deal with his presence? it sounds as if he is in serious condition and he is undergoing surgery and will be there for a while. what arrangements has the

hospital put in place to deal with this? >> reporter: that's a really good question. this is a man that authorities are calling a terrorists who was intent on killing people, so you can imagine the feelings of concern from patients in the hospital. in fact we know that some of the victims from monday's bombing are actually here at the hospital. at last check there were 12 victims from the bombing being treated at this hospital. as we have pointed out, there are security officers here and there's a fairly large presence. it appears the hospital is taking every measure necessary to insure that patients and everybody here are safe. >> any indication when he will well enough, when he will be sufficiently recovered to speak with authorities? i imagine there are fbi officials that really want to talk to him. >> reporter: oh, absolutely. i mean, this is very serious. they want to be able to

interview him and make sure that he survived so they can get the answers and find out what the motive is and all the information they need to piece everything together. i can imagine that there is an intensive treatment going on right now, but we don't really have any more details about when he is going to be fully recovered or anything like that. probably won't know that until there is a press conference held. at last check, he is in serious condition. he possibly substained substantial blood loss for 24 hours, and there are indications that he was first injured yesterday morning in a shoot-out with police, and then there is the potential that he was injured again in another gun fight when authorities discovered him at the boat. we do know that, but no indication about when he could be fully recovered. >> it's a surreal situation that

dzhokhar is in the hospital with the people injured. >> you say it's a surreal situation. with that in mind members of the media and the public eagerly awaiting the press conference to be held by the fbi where we hope to get more information on dzhokhar's condition. a couple moments ago, our correspondent asked some questions. >> what we are trying to do is determine if the two young men had support domestically or abroad. and there is significance to that, because we need to see anything before this was carried out. >> reporter: he is in the boston hospital tonight being treated, and so many people are thankful

that he is alive because he will be able to answer many, many questions. walk me through the process of how investigators will go about talking to him and presumably also shifting through treasure trove of evidence that they got out of the cambridge apartment earlier today. >> the first thing we have to to do is allow him to respond intelligently, number one, and then the other part of the process is to derive information from him that will give us answers to questions that we are seeking, like, did he have support anywhere in the metropolitan area of boston, and did he have knowledge of his brother's training overseas, and was there support? was there aid or abetting in the boston area? i mean, they are just going to run through a whole series of questions and they are going to try and give us a motive and the means in which they carried this out. by means, i refer specifically

to any type of support they may have received, because that is very, very significant going forward in an attempt to anticipate a repeat of this type of incident. >> this all ended relatively well and relatively quickly, but given the fact that the older brother, tamerlan, he was interviewed by the fbi back in 2011, do you think that something fell through the cracks here? >> i was afraid you were going to ask me that. i mean, obviously, you know, i can't speak intelligently as to exactly what the fbi or the intelligence community did or didn't do in their interviews, but obviously i would say that there was legitimate cause for concern that was expressed to our government, and whether or not we managed it properly is going to come under the microscope now, because as you are aware, it's all over the media. >> now the legal process begins

and already controversy. a kwrusice department official told us that the government has invoked the so-called public safety exception in its questioning of dzhokhar. and now, we should note that a very smart attorney here in the united states says that exception may now be a shakily legal ground and could spell early trouble for prosecutors. >> the first thing his lawyer will do is challenge federal jurisdiction. he will say this is an ordinary murder. the killing of the police man and the shooting of the other police man doesn't seem to be any part of terrorism, and the federal terrorism statute generally applies to international terrorism, and we have no evidence at the moment

that it requires the intention be to coerce the government, and it has a whole series of things that make it into terrorism. the lawyers will challenge whether this is federal because they rather have it be a state charge, and no death penalty in massachusetts. yes, federal death penalty but there has to be federal jurisdiction. >> if they win the argument and he is found guilty in massachusetts under their state law, what will happen? >> life in prison. >> in massachusetts? >> in massachusetts. and they could charge conspiracy to murder. >> the running theme today seems to be the older brother was the very domineering type that became emersed in much more islamic fundamentalist beliefs, and coerced the younger brother who never had traced this belief

before. is that a defense? >> it is to a federal crime. because they need to prove he intended to coerce the government or intimidate, and if he says i went along with my brother, my intent was to please my brother, that would question whether it's federal. and you could charge him with conspiracy. and conspiracy doesn't carry the death penalty. >> would you have been free to defend someone in this position from a legal point of view? >> from a legal point of view. the government made a mistake by clinging to the public safety miranda, when the police said there is no public safety issue, it's solved and there are no further threats, and the fbi are

saying there's enough threats, they should have given him miranda. his kwryouth, and he seems to b influenced by his brother, and he could hold out and try to get a deal if he is prepared to say whether his brother got training in chechnya. he doesn't have very many cards to play. >> graham wants -- >> that's impossible. nobody could be tried as an enemy combatant. couldn't happen. >> in terms of the revelation, you have the two brothers who committed this appalling act, and the younger one in particular seems to have been leading a very regular american life, does that concern you as an american that there may be many more out there? this could be a start of a whole

new wave of terror? >> you don't want to be critical of what law enforcement did, they did a phenomenal job, but the fact that one young man can shut down an entire city, and get baseball games postponed, and another young man can say i want to have that power as well, and people are influences by previous experiences and older brothers and authority figures. >> that was a very good point that he made right at the end about the fact that it was just one guy who effectively closed down the city of a million or so people, an unprecedented security crackdown. we will take a break. when we come back, we will take a look at the crackdown, the security operation which finally got the boston bombing suspect. for all kinds of reasons. t

this is cnn breaking news. >> you are watching cnn's continuing coverage of the capture of the second suspect in the boston marathon bombings. >> and let's get the latest after a very dramatic day here in the united states. [ applause ] >> you hear the cheers for boston's finest on friday night, a standing ovation for federal and local authorities after they captured the second suspect in boston's marathon terror attack. but it did not happen peacefully. gunfire erupted after the police had dzhokhar cornered in a

neighborhood. it ended with him being transferred to a boston hospital. take a look at him in this photo in the back of an ambulance. he is listed in serious condition. and the greater boston area under lockedown for friday, businesses and schools were closed and residents were told to stay at home. and the drag net involved millions of people and in the u.s. it was almost unprecedented. >> officials are going to study this at quite sometime, because officers did something not quite done before. they had a capture net for the suspect and enlisted the help of the 4.5 million people. the population of the whole city to help them. here is how they did it. they figured out where they thought they would be, in one of six towns, 600,000 people living there, and they said lock the doors and go inside and clear

the streets so nobody is moving, and then they focused on watertown in particular. they said keep your doors locked and flooded the zone with police officers and they started cutting off all access in and out of the area. how did they do that? among other things, they asked 5500 taxi drivers around boston, stay away. don't go there. they shut down subways and buses and asked many businesses to close, and fenway park cancelled the ball game. they shut down schools, public schools, private schools, and universities like harvard and mit, all shut down. and beyond that they put pressure on the trains to not let people hop on and get out of town easily and even more security at the airport. you can see what is happening around watertown here. they put up a net, a capture net, and they started squeezing and the belief that this man was now caught in the middle of it all, and now let's put it all

away and zoom into where he was found because that was the real proof in the plan. they said if they can keep him there and keep asking people to look, somebody would spot him. and that house with the red car behind it, that's what happened. a man looked out into the backyard where he had his boat. what did he see? he saw a smear of blood on the cover of the boat and looked inside according to authorities and saw somebody hiding there and called the police, and that's how this extraordinary manhunt ended. >> thanks to tom foreman for that. the tsarnaev brothers left many injured in their wake. one mit man shot, and he was 26 years old. and then 178 people wounded at the marathon by the bombs and 60 remain in area hospitals. three people were killed,
